Silverlight TabItem content not scrolling

Question

我有這個XAML，我試圖讓TabItem的內容滾動（沒有成功）。

<ex:TabControl> 
    <ex:TabItem Header="General"> 
    <ContentPresenter Content="{Binding }" ContentTemplate="{StaticResource tabMenuItem}" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto" /> 
    </ex:TabItem> 
    <ex:TabItem Header="Prices (Item)"> 
    <ScrollViewer VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Auto"> 
     <ContentPresenter Content="{Binding NonModifierPricesView}" ContentTemplate="{StaticResource tabMenuItemPrices}" /> 
    </ScrollViewer> 
    </ex:TabItem> 
</ex:TabControl> 

當我的TabControl得到調整，讓TabItem的是太小，無法顯示全部內容，不顯示滾動條。我在某處做錯了什麼？

編輯：爲tabMenuItemPrices

<DataTemplate x:Key="tabMenuItemPrices">

的ScrollViewer中的孩子需要管理它自己的高度和寬度要求XAML。在你的ContentTemplate你最外面的電網未指定的Horizo​​ntalAlignment或VerticalAlignment所以它的默認爲拉伸值...你可以嘗試設置對齊到左頂部如下：

<Grid HorizontalAlignment="Left" VerticalAlignment="Top"> 

底線是，控件模板中最外面的容器必須將它的高度和寬度設置爲它的內容，而不是父容器。
